[Feature] Artifact Streaming for Linux

### NOW GA!
Note: This is an estimate and is subject to change

---

Previously known as Teleport, Artifact Streaming will enable customers to store the container images within a single registry, manage, and stream the container images to Azure Kubernetes Service (AKS) clusters in multiple regions. Artifact Streaming will deploy container application to multiple regions without having to create multiple registries or enable geo-replication.

[Azure Container Registry (ACR)](https://azure.microsoft.com/products/container-registry/) and [Azure Kubernetes Service (AKS)](https://azure.microsoft.com/products/kubernetes-service/) will soon support artifact streaming. Artifact streaming for AKS provides customers the ability to accelerate containerized workloads in the cloud by dramatically reducing the overall startup time by almost 15% when connected to ACR.

Artifact streaming will empower customers to scale resources on AKS seamlessly by not having to wait for long pull times for each Kubernetes pod. Customers with Linux amd64 container images will be supported and we have plans to support Windows and arm64 container images in the future.

The ACR and AKS team would also like to give a huge thanks to Alibaba for their contributions to the [containerd Overlaybd project](https://github.com/containerd/overlaybd).

We can’t wait to hear what our customers have to think and look forward to hearing feedback on further improving this feature.
